TOOL FOR STRAIGHTENING TEETH ON CARDlNG-ROLLS.

SPECIFICATION forming part of Letters Patent No. 733,894, dated July 14, 1903,

Application filed November 5, 1901. Serial No. 81,220. (No model.)

To ail whom it may concern:

Be it known that I, NOAH GIIUFFSTICKLER, a citizen of the United States, residing at Mount Holly, in the county of Gaston and State of North Carolina, have invented a new and useful Tool for Straightening Teeth on Oarding-Rolls, of which the following is a specification.

This invention relates to a tool for straight- 1O ening bent teeth of carding-rolls, and has for its object to present an exceedingly-simple, thoroughly-efiioient, and easily-operated device of the character specified which in operation will evenly and rapidly raise and straighten teeth that may have become bent or mashed down.

With these and other objects in View, as will appear as the nature of the invention is better understood, the same consists in the no novel construction and combination of parts of a tool for straightening the teeth of carding rolls, as will be hereinafter fully described, and specifically pointed out in the claims. I

In the accompanying drawings, forming a part of the specification, and in which like numerals of reference indicate corresponding parts, there is illustrated a form of embodiment of the invention capable of carrying the same into edect, it being understood that the elements herein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the scope of the invention.

In the drawings, Figure 1 is a view in perspective of the tool. Fig. 2 is a View in side elevation, the head portion of the tool being in section. Figs. 3 and 4t are views in side elevation, exhibiting the manner in which the tool is employed in straightening the cardingroll teeth.

Referring to the drawings, 1 designates the handle of the tool, the rear portion of which is suitably rounded and curved to conform to the hand of the user and the front portion of the handle being bent upward to present approximately a gooseneck 2. On the under side of the handle, near the front end thereof, is secured a resilient plate 3, constituting a gage-plate, the gage-plate being associated with the handle in this instance by a rivet 4, although it may be otherwise secured thereto and still be within the scope of the invention. From its point of attachment to the handle the plate diverges outward on curved lines and terminates in a broad straight edge 6, which extends at right angles to the length of the handle, the plate being slightly curved upward, as at 7, to afford ample space in which the teeth may move when the tool is being manipulated.

Secured to the inner side of the gooseneck by a rivet 8 is a plate 9, constituting the lifting-plate, the corners of the plate adjacent to the handle being rounded and the lower side of the plate terminating in an edge 10 of the same width as and lying exactly parallel with the outer edge of the plate 3.

At a point on the handle near the outer end thereof there is provided an opening which is engaged by a set-screw 11, the set-screw to bear upon the plate 3, whereby to permit adjustment of its outer edge with that of the plate 9, thus to adapt the tool for raising or straightening teeth that are only slightly bent or are mashed down upon the roll.

In using the tool the plate 9 is passed in front of a tooth and the plate 3 back of it, with the free terminal of the plate 9 disposed close to or in the bend of the tooth and the free terminal of the plate 3 bearing against the end portion of the tooth, as clearly shown in Figs. 3 and 4t, and by lifting the handle the tooth will be brought into proper position. If the tooth be mashed flat upon the carding-roll and its point he also bent out of position, the tool will first be worked either forward or backward, as the case may be, to lift the tooth away from the cardingro1l,and then by lifting or depressing the 0 handle, as the case may be, the point will be bent to its proper angle. As herein shown, the plate 9 is displayed as bearing against the front of a tooth and the plate 7 against the rear thereof; but it is to be understood that 5 the position of the tool may be reversed and still perform its proper functions.

It'is to be understood that the gage-plate 3 will be adjusted, according to the size of the tooth, always to bring the free terminal of the plate 3 against the end portion of the tooth and with the free terminal of the plate 9 disposed in the bend of the tooth.

While the device of this invention is exceedingly simple of construction, it will be found thoroughly efficient in use and will in an efiective manner supply a long-felt want.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Adevice of the character specified, comprising a handle having one end curved to present a gooseneck, a lifting-plate carried by the gooseneok, a gage-plate carried by the handle, the operative edges of the two plates being in parallelism, and an adjusting-screw
